IMPRQVED MACHINE FOR WASHING- AND SCOURING SAND AND OTHER SUBSTANCES.

The Schedule referred to in these Lettere Patent and making para of the same.

To all lwhom it may concern 1i Beit known that I, J onu TAYLOR., of Gonnellsville, in the county of Fayette, and State of Pennsylvania., have invented a new and useful Machine for Seoul-ing, Washing, and Conveying Sand to a platform, or into cars, without-manual labor; and I do hereby declare that the following is a full andexact description thereof, reference Vbeing had to the accompanying drawing, making a part of this specification, in which- Figure 1 is a perspective view of my machine;

Figure 2 is a sectional elevation, as formed by a plane passing longitudinally along the iirst washing-trough, as presently to be described;

Figure 3 shows, in perspective, the construction of the stern, wheels', and buckets, which operate lin each washing-trough; and

Figure 4 is a full and somewhat enlarged View of one of the buckets.

Like letters of reference indicate like parts in each.

The nature of my inventionl consists, first, in the construction of a sand-washing and scouring machine, having one 4or more troughs inclined in a direction thc opposite of that in which the` sand is to be carried, and in each trough, a reciprocating stem, mounted on wheels or otherwise, so as to operate with small loss by friction, on the under side of which stem or stems are attached buckets, which operate close to the sides and bottom of the trough or troughs, and which are attached to the stem in suoli wa that, in reciprocating back and forth in their respective troughs, they shall carry the sand upward but not backward; and

It consists, furthermore, in the combination. of such devices with each other, and with a grinding-roller operating in a concave, whereby, in connection with the action of a stream or iiow of water, the sand is thoroughly scoured, washed, and discharged from the machine in av suitable condition for' use in the arts.

In the manufacture of glass and glass-ware, and for some other purposes, sand is required, as free as possible from all the impurities which are to be found in it as it is dug or quarried. Such impurities, or many of them, can be best removed by washing the sand in a stream of water, which inode of cleansing can be materially aided by bringing the grains of sand into intimate frictional contact, thereby more perfectly releasing from union with the sand,l the soluble impurities, which impurities the water takes up and carriesaway.

To enable others skilled inthe art to make and use my invention, I will proceed `to ,describe its construction and mode of operation. i

a is a trough, with close sides and bottom, and with the latter' inclined somewhat ina direction the opposite of that in which the sand isyto be carried.

This, with the other devices,\is set in any suitable frame, A. f

The inner sides of this trough are grooved or shouldered, as at a', to afford a track for the wheels b.

These wheels, b', by their axles b, carry a stem, b, which is made so as to operate, bya reciprocating motion, back and forth lengthwise of the trough a.

By a hinge or other suitable jointesuch is shown at c, I attach to the stem l, and at suitablel distances from each other,I a series of buckets, d', which, when in operation, will work almost in contact with the sides and bottom of the trough.

The lolut cis such that the buckets d may swing freely forward, that is, toward the higher end of the trough, but not backward; or, to secure the same end, I insert braces or stays, c, in the lower face of the stem t, and one just back of each bucket d, and in such relation thereto that such brace e will prevent the backward swing or movement of the bucket immediately in front.

A reciprocating motion is imparted to the stern'b by a crank, B, rocking shaft, B', and suitable connectingrods, as shown, or by other apparatus ordinarily used for similar purposes. Sand is then fed into the trough c, a stream, jet, or dow of water passed in, andthe stem b put in motion. lVith its forward or upward strokethe buckets e being supported by braces e from behind, as described, will carry up all sand in front of them. With their backward stroke, they will swing forward. pass back over any sand that ma), be in the rear of them, and again move up, each bucket taking a new load.

The water, in the. mean time, dissolves the soluble.

and washes away the lighter insoluble impurities that may bein the sand, and carries them off by a sluice, or gate, at the lower end of the trough a, not shown in the drawing.

rlhe upper bucket of the series discharges the sand into a concave trough, f', in which operates a revolving cylinder, f, the working-faces of the two being so close together that the sand fed therein is subjected to a grinding-process, or, iu other words, the grains of sand are brought into such intimate ictional contact that thereby the impurities will be still further looscned from their union with the sand, and by a stream of water fed in at the same time, will be taken up or washed away, as already described.

The cylinder and concave are so set as to incline toward the spout y, where thc sand and water are discharged into a cistern, g. The excess of water ows off through the spout 7i., and fresh water is .fed in.

In the troughs ZZ, which may be either inclined or horizontal, or a part inclined and a part horizontal, I arrange another stem or stems, m m', with wheels, buckets, braces, die., as before, and operating in the same way.

As the sand is carried forward and upward, in the trough m, the impurities are carried away by a stream or flow ofv water, fed therein at any desirable point, the excess of .water being carried ch" at a spout, h.

The sand is carried along ahorizontal trough, l', any

desirable distance, and discharged through trap-doors in the -bottom closed by the slides o, or carried over the further end, on to a platform or ear, as may he most convenient for use Aor shipment.

The stems fm mf receive a vibratory or reciprocating motion by a crank-shaft, p, which connects with the rocking shaft B'. i

In making the machine described, any suitable niaterial orniaterials may be used. The cylinder and concave are preferably made of cast-iron. Motion may be imparted to them by a pinionou the end of its axle meshing into the gear-wheel s.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a sand-Washing machine, a series of reciproeating buckets, operating in a trough or troughs, and attached to a stem or stems in such way as to carry the sand forward but not backward, while the latter is being cleansed of its impurities by a stream or iiow of water, fed into the trough or troughs, substantially as set forth.

2. The grinding-rollerf operating in a concave, f', for scouring sand, when used in combination with stems, buckets, and troughs, substantially as and for the purposes hereinbefore set forth.
